Abstract :
Ferrites of ZnxMg1-xFe2-yGdyO4 (x=0, 0.2, 0.4, 0.8 and 1.0; y=0, 0.05 and 0.1) were prepared by usual solid state standard ceramic method. Characterizations were made by X-ray diffraction method and FTIR spectroscopy. Magnetic properties like temperature dependence normalized AC susceptibility and Curie temperature were studied. This study reveals that MgFe2O4 exibits multi domain structure with high Curie temperature On substitution of Zn2+ , it is found that Multi Domain (MD) structure changes to Single Domain (SD). Curie temperature also found to decrease due to decrease in A-B intraction. On substitution of Gd3+ in Mg-Zn ferrite system peak obtained in MgFe2O4 is supressed which is attributed to decrease in grain size and further decrease in Curie temperature is attributed to the decrease in B-B interaction.This is because Fe-Fe interaction is greater than Gd-Fe interaction at B-site
